Title

The BlackBerry UEM 12.7 server must be configured to have at least one user in the following Administrator roles: UEM Security Administrator, Auditor, and one or more Site Custom Administrator or UEM predefined enterprise/help desk roles. (Cat II impact)

Discussion

Having several administrative roles for MDM server supports separation of duties. This allows administrator-level privileges to be granted granularly, such as giving application management privileges to one group and security policy privileges to another group. This helps prevent administrators from intentionally or inadvertently altering other settings and configurations they may not understand or approve of, which can weaken overall security and increase the risk of compromise. - Server primary administrator: Responsible for server installation, initial configuration, and maintenance functions. Responsible for the setup and maintenance of security configuration administrator and auditor accounts. Responsible for the maintenance of applications in the MAS. (Called "Security Administrator" in UEM) - Security configuration administrator: Responsible for security configuration of the server, defining device user groups, setup and maintenance of device user group administrator accounts, and defining privileges of device user group administrators. (UEM Enterprise Administrator, Help Desk Administrator or custom roles can be used for this role) - Device user group administrator: Responsible for maintenance of mobile device accounts, including setup, change of account configurations, and account deletion. Responsible for defining which apps user groups or individual users have access to in the MAS. Can only perform administrative functions assigned by the security configuration administrator. (UEM Enterprise Administrator, Help Desk Administrator or custom roles can be used for this role) - Auditor: Responsible for reviewing and maintaining server and mobile device audit logs. (These is no predefined role in UEM) SFR ID: FMT_SMR.1.1(1)

Review the BlackBerry UEM 12.7 server configuration settings, and verify the server is configured with the Administrator roles: a. UEM Security Administrator b. Auditor c. One or more Site Custom Administrator or UEM predefined enterprise/help desk roles Note: The exact name of the role is not important. Each role should include functions close to the role descriptions listed in the VulDiscussion. Note: The intent of the requirement is that there be separate people performing each administrator role; few users are assigned to the UEM Security Administrator role; the auditor role is limited to only authorized permissions; and day-to-day management of user accounts, group accounts, and profiles are performed from site specific custom administrator roles or UEM predefined enterprise/help desk roles instead of the UEM Security Administrator. On the BlackBerry UEM 12.7, do the following: 1. Log in to the BlackBerry UEM 12.7 console and select the "Settings” tab at the top of the screen. 2. Expand the General settings tab on the left pane. 3. Expand the Administrators tab on the left pane. 4. Select the Roles tab on the left pane. 5. Verify there is at least one user assigned to each of the following roles: a. UEM Security Administrator b. Auditor c. One or more Site Custom Administrator or UEM predefined enterprise/help desk roles Verify the auditor role function is limited to only reviewing and maintaining server and mobile device audit logs as follows: 1. Log in to the BlackBerry UEM 12.7 console and select the "Settings” tab at the top of the screen. 2. Expand the Administrators tab on the left pane. 3. Select the Roles tab on the left pane. 4. Click on the Auditor role. 5. Verify the role only has the following permissions assigned: - View audit information - Delete BlackBerry Dynamics audit log files - View and export BlackBerry Dynamics audit log files - View audit settings - Edit audit settings and purge data - Edit logging settings Talk to the UEM Security Administrator and verify custom administrator roles / UEM predefined enterprise/help desk roles are used for day-to-day management of user accounts, group accounts, and profiles. If at least one user is not associated with the UEM Security Administrator, Auditor, and one or more site custom administrator roles/UEM predefined enterprise/help desk roles, this is a finding. If the auditor role has more permissions than authorized, this is a finding. If day-to-day management of user accounts, group accounts, and profiles is primarily performed by UEM Security Administrators instead of one or more site custom administrator roles/UEM predefined enterprise/help desk roles, this is a finding.
